"Music is the lifeblood of so much of what we do at Clear Channel, and our listeners are the reason for everything we do. We're focused on making the iHeartRadio Music Festival an experience that excites and electrifies music fans nationwide -- and with a line-up like this, we believe we'll exceed all of their expectations," said Bob Pittman, CEO of Clear Channel. "The iHeartRadio Music Festival is an indication of Clear Channel's ongoing commitment to music and artist development -- maximizing artists' exposure to fans and audiences nationwide. With our broadcast brands, live events and the iHeartRadio digital platform, in combination with our relationships with artists, labels and most importantly our listeners, we continue to reinvent the music experience in a way that no other company can."

"The iHeartRadio Music Festival 2011 was such an amazing experience for our listeners, and just like the iHeartRadio digital radio service, really showcased top artists across all genres of music," said John Hogan, Chairman/CEO of Clear Channel Media and Entertainment. "The bar was set high this year given the overwhelming success of last year's inaugural event and we are extremely pleased to have the opportunity to again deliver a diverse, extraordinary line-up of incredible talent to our listeners for year two of the iHeartRadio Music Festival."

"The iHeartRadio Music Festival is the ultimate celebration of what's hot in all genres of music, from rock, pop and country to electronic dance music, R&B and hip hop," said Tom Poleman, President of Clear Channel National Programming and Executive Producer of the Festival. "For the first time, fans from across the country will get to see today's megastars like Rihanna, Taylor Swift and Usher on the same stage as legends like Aerosmith, Mary J. Blige and Bon Jovi. I'm sure we'll have hundreds of memorable moments throughout the festival. It's the concert line-up of the year for both fans and artists."

"The iHeartRadio Music Festival is a unique celebration of music -- it's the biggest names in the industry coming together for an impressive weekend of live entertainment," added Seacrest. "The momentum, energy and music experience around the inaugural iHeartRadio Music Festival was incredible, and I'm excited to be a part of this must-see event."
